Devanahalli pomelo

It is exclusively grown in the region around Devanahalli taluk, Bangalore Rural District, India, as an exotic crop variety.

It was registered by the Controller General of Patents, Designs, and Trademarks under the title "Devanahalli Pomello" and recorded at GI Application number 131 under Class 31 as a horticulture item.

[1][2] The fruit was initially grown in villages around Devanahalli taluk, including Beerasandra, Bidalur, Chanarayapatna, Kundana, Melinathotadahalli, Neelaganapalya, Neelaguntepalya, Raghunathapura, Rajathafarm, Shivanapura, Soopanahalli, and Vishwanathapura and some regions in India.

[1] After a large land acquisition to build the Kempegowda International Airport, the plant is now grown only in a few, non-contiguous villages.

Five decades ago, this plant's special sweetness trait was compromised by natural crossbreeding with local varieties, and it was nearing extinction.

[1] This plant has faced a serious threat in recent years of near extinction due to construction of the Bengaluru International Airport at Devanahalli.

[3] The Department of Horticulture also established a conservation biocentre at Hulimavu to assist in distributing plants to the remaining farmers.

The flowers are sweet-smelling, and fruits are formed in globular, egg, or pear shapes, with the width varying from 10–30 centimetres (3.9–11.8 in).

In a nursery in Devanahalli, grafting is done by an organic farming method which takes about three months, and about 400 saplings are marketed in a year.

[4] After fine tilling and kneading of the soil, the plant grafts are placed in pits measuring one meter on each side.
